High Volatility and Big Price Change Scanner

This Pine Script scans for high volatility and significant price changes on the chart. It uses Average True Range (ATR) to measure volatility and calculates the percentage change in price over a specified lookback period. When both conditions—high volatility (ATR above a threshold) and a significant price change (greater than the set percentage threshold)—are met, a signal is plotted below the bar. Additionally, an alert condition is included for notifications when these conditions are satisfied.

This script is useful for identifying stocks with large price movements and increased volatility, which may indicate potential trading opportunities.
